Nearly 1 in 8 Arizona drivers are uninsured, according to recent estimates. This means the risk of being hit by someone without insurance is real. When you’re involved in an accident with an uninsured motorist, your medical bills, vehicle damage, and lost wages do not simply disappear. Arizona uninsured motorist coverage can provide important protection in these situations. Understanding how your UM coverage works can make a meaningful difference in how much of your loss is actually covered versus paid out of pocket. This guide explains how Arizona uninsured motorist coverage protects you, what types of coverage exist, and what steps to take if you’re hit by an uninsured driver.

What Is Uninsured Motorist Coverage in Arizona?

The Basics of UM Coverage

Uninsured motorist (UM) coverage is an optional add‑on to your auto insurance policy in Arizona. It is designed to protect you when the other driver has no liability insurance. In effect, it acts as a financial safety net when the at‑fault driver cannot pay for your injuries and damages through an insurance policy. When you make a UM claim, you pursue benefits under your own policy rather than the other driver’s policy.

Depending on your policy, UM coverage can help pay for medical expenses, lost wages, pain and suffering, and other injury‑related damages. It generally applies to you as the policyholder and, in many policies, to your resident family members and passengers in your vehicle during the accident. Without UM coverage, you could end up relying on your own health insurance and personal resources or pursuing a lawsuit against an uninsured driver who may not have assets to satisfy a judgment.

Arizona’s Insurance Requirements

Arizona law requires all drivers to carry liability insurance with minimum limits of $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage. Many drivers carry only these minimum limits, and some drive without any insurance at all. Arizona insurers must offer UM and UIM (underinsured motorist) coverage, and policyholders who decline it must typically do so in writing. Because serious injuries can quickly exceed minimum liability limits, UM and UIM coverage are often recommended as additional protection.

UMBI vs. UMPD: Understanding Your Coverage Options

Uninsured Motorist Bodily Injury (UMBI)

Uninsured motorist bodily injury (UMBI) coverage is the most common form of UM protection. UMBI addresses injury‑related losses in accidents caused by uninsured drivers. Covered damages can include:

If you are injured in an accident with an uninsured driver, UMBI can help you access and pay for necessary medical care, subject to policy limits and terms. The coverage typically applies to you and, depending on your policy, to certain passengers in your vehicle at the time of the crash.

Uninsured Motorist Property Damage (UMPD)

Uninsured motorist property damage (UMPD) coverage is intended to address damage to your vehicle and, in some cases, other property caused by an uninsured driver. It may pay repair costs or the actual cash value of your vehicle if it is declared a total loss, up to your coverage limits. UMPD is less commonly purchased than UMBI because many drivers rely instead on collision or comprehensive coverage, but it can be particularly important if you do not carry those first‑party coverages. Reviewing your declarations page can confirm whether UMPD is included in your policy.

How UM Coverage Works After an Accident

When you’re hit by an uninsured driver, using your UM coverage generally involves a series of steps:

  1. Make safety your first priority and call 911 if anyone is injured. Request emergency medical care if needed.
  2. Document the scene with photos or video, capturing vehicle positions, damage, skid marks, traffic controls, and roadway conditions. Obtain the other driver’s information and contact details for any witnesses.
  3. Report the accident to your insurance company as soon as reasonably possible. Many policies require prompt notice, sometimes within a specified time frame, but you should check your policy for exact requirements.
  4. Report the collision to law enforcement if there is injury, death, or significant property damage, consistent with Arizona’s reporting laws. A police report can be important evidence for your UM claim.
  5. File a UM claim with your insurer, providing the police report, medical records, repair estimates, proof of lost income, and other documentation of your damages. Your insurer will investigate liability and damages before making an offer.

Arizona law and your policy impose deadlines on UM claims. Statutory provisions, as well as contractual time limits, can apply, so waiting multiple years can jeopardize your rights even if the statute referenced is three years or more. Because these timing rules can be technical, many people contact a personal injury attorney early in the process to help protect their claim and respond to insurer requests. Insurers sometimes offer low settlements to unrepresented claimants or move quickly to resolve claims before the full extent of injuries is known.

Common Questions About Arizona Uninsured Motorist Coverage

What if the other driver is underinsured instead of uninsured?

If the at‑fault driver has liability insurance but the limits are too low to cover your full damages, underinsured motorist (UIM) coverage may apply. UIM coverage can help pay the difference between the at‑fault driver’s policy limits and your documented losses, up to your UIM limits. For example, if the other driver’s policy pays $25,000 but your damages are reasonably valued at $100,000, your UIM coverage may help address some or all of the remaining $75,000, depending on your policy.

Does UM coverage apply to hit‑and‑run accidents?

In many Arizona policies, UM coverage applies to hit‑and‑run collisions where the at‑fault driver cannot be identified, subject to specific conditions such as prompt reporting. Typically, you must report the accident to law enforcement and notify your insurer within the time frames specified in your policy. A police report can strengthen your UM claim by documenting that the collision occurred and that the other driver left the scene.

Can I use UM coverage if I’m partially at fault?

Arizona follows a comparative negligence system. You may be able to recover damages even if you are partially at fault, but your recovery is reduced by your percentage of fault. If an arbitrator, judge, or jury finds you 20% responsible for the crash and your total damages are $100,000, your net recovery could be reduced to $80,000. Comparative fault principles apply whether you are seeking recovery from another driver’s insurer or under your own UM/UIM coverage.

What if I don’t have UM coverage?

If you do not have UM coverage and are hit by an uninsured driver, you may end up relying on your own health insurance and personal funds, or you may pursue a lawsuit against the driver. In practice, many uninsured drivers have limited assets, so collecting on a judgment can be difficult. This is why many consumer resources and attorneys strongly recommend purchasing UM and UIM coverage. If you realize you do not have UM now, you cannot apply it retroactively to a past crash, but you can contact your agent to discuss adding it for future protection.

How much UM coverage should I carry?

Many insurance professionals suggest at least matching your UM/UIM limits to your liability limits so your protection for others and for yourself is comparable. For example, if you carry $100,000 per person / $300,000 per accident in liability coverage, you might consider the same UM/UIM limits. The appropriate amount depends on your income, assets, and risk tolerance, so it is wise to discuss options with your insurance agent or broker.

Will filing a UM claim increase my insurance rates?

Many insurers state that they do not increase premiums solely because a policyholder makes a UM claim for an accident they did not cause. However, underwriting decisions can depend on multiple factors, including your claims history and the carrier’s internal guidelines. Reviewing your policy and asking your agent how UM claims are treated by your particular company can give you more clarity.

Next Steps: Protecting Yourself and Your Rights

If you have not yet been in a collision with an uninsured driver, review your auto insurance policy to confirm your current UM and UIM limits and consider whether they are sufficient for your needs. If you have already been hit by an uninsured driver, focus on your medical care and document everything related to the crash and your recovery, including bills, receipts, time missed from work, and any out‑of‑pocket expenses. Before accepting any settlement from your insurer, consider having a personal injury attorney review the offer to assess whether it reasonably reflects your damages.
